After looking at all the articles on Steemit I sometimes believe that people don't realise that blockchain never forgets.
So either you stay anonym as far as it is possible in the world wide web or you really think about what you post in here :)
Most people are connected with their facebook account in here, so they could be connected easily with their real life ID. I don't know if Steemit will use those info anytime. (Didn't find any info about that.) But it is possible imo. Please correct me if I am wrong.
So here is my advice :)
